Kids also learn nothing about the importance of a positive outlook, especially how it affects other people. They don't learn about setting goals, or managing risk, or discerning the difference between truth and lies in the media and in person.
You could make your own long list of skills that kids aren't taught during the time they are learning things they will never use. Yes, yes, yes, I understand that some of the subjects taught in school are meant to increase critical thinking and generally expand minds as opposed to teaching useful facts, but isn't there a way to accomplish the same thing with topics that ARE useful?
I'm in the process of building a house. (This is year 3.5 of the process, and ground was broken just yesterday.) While the project is frustrating, it is also intellectually fascinating. I had no idea how many technical disciplines would be involved. There's even an engineer who specializes in knowing how to move the dirt from one part of the property and fill in a hole in another, packing it down in just the right way to make it stable for the foundation.
You could take any tiny portion of the house project and make it an exercise in critical thinking. I can imagine a school curriculum organized around building an imaginary house, advancing from first grade through high school. Kids could learn all sorts of useful skills, from budgeting (math), to calculating loads (science), to learning how couples can decide on the fixtures and furniture. Your geography course could be based on deciding what country to build your house in. Geology would be oriented toward deciding what type of land to build on. Art class would involve interior design and architecture, with a semester on how to identify good art for the walls. Biology would involve understanding your own future garden and plants. Evolution would involve learning why your family dog walks on four legs and you walk on two.
You would learn all the critical thinking you ever needed just trying to design a kitchen that requires the fewest footsteps and fits into a defined space, with a limited budget.
Kids who are gifted would learn more about the math and science behind the engineering of the house. Kids on a more hands-on career path might be learning how to pave the driveway or design the electrical system. Designing and building a house employs almost every useful field of knowledge, excepting maybe history and language.
Maybe we wouldn't be in this economic mess if all kids had to learn about budgeting, mortgage loans, and risk analysis.
